Pelodiscus sinensis, commonly known as the Chinese soft-shelled turtle, possesses abundant collagen, proteins, and amino acids in its shell muscle. sinensis has been historically utilized a valuable traditional medicine. While consume meat of internal visceral organs are typically discarded. The contain components, including 8%-15% collagen 8% blood. This study focused on extracting from organs...

The cell membrane provides critical cellular functions that rely on its elaborate structure and organization. The structure of turtle membranes is an important part of an ongoing study of erythrocyte membranes. Using a combination of atomic force microscopy and single-molecule force spectroscopy, we characterized the turtle erythrocyte membrane structure with molecular resolution in a quasi-nat...

The cDNAs encoding lactate dehydrogenase isozymes LDH-A (muscle) and LDH-B (heart) from alligator and turtle and LDH-A, LDH-B, and LDH-C (testis) from pigeon were cloned and sequenced. The evolutionary relationships among vertebrate LDH isozymes were analyzed. Contrary to the traditional belief that the turtle lineage branched off before the divergence between the lizard/alligator and bird line...

In this paper we describe Turtle, a peer-to-peer architecture for safe sharing of sensitive data. The truly revolutionary aspect of Turtle rests in its novel way of dealing with trust issues: while existing peer-to-peer architectures with similar aims attempt to build trust relationships on top of the basic, trust-agnostic, peer-topeer overlay, Turtle takes the opposite approach, and builds its...

■ Abstract A critical reexamination of turtle relationships continues to support a sister-group relationship of turtles with a clade of marine reptiles, Sauropterygia, within crown-group Diapsida (Sauria). The high Homoplasy Index raises concerns about the phylogenetic information content of various morphological characters in broadscale phylogenetic analyses. Such analyses may also suffer from...

Interactions with sea turtles have occurred at an alarming rate in swordfish longlining in Hawaii in recent years and various regulations have been put forward to protect sea turtles. In order to understand the cost of reducing sea turtle interactions, methods have been developed to derive the shadow price of sea turtle bycatch based on fisher's welfare loss from a specific regulation. This pap...

Sea turtle interactions with the longline fishery in Hawaii have become a serious concern in recent years. Various measures, including a swordfish harvest ban, have been adopted to protect sea turtles. This study explores the factors and degree of sea turtle interactions with Hawaii’s pelagic longline fishery, i.e. the production of undesirable outputs in the pursuit of an economic activity, in...

I. Adenosine triphosphate-creatine phosphotransferase (EC 2.7.3.2) from turtle (Pseudm?ys scripta) heart occurs in two major electrophoretic forms: one cytoplasmic (p1 = 6.67) and one mitochondrial (p1 = 7.37). 2i. In the forward direction (phosphocreatine + ADP + ATP + creatine), NADH actcvates the purified cytosol enzyme by lowering the K,,, for phosphocreatine almost thr e-fold. 3. From thes...

The turtle body plan differs markedly from that of other vertebrates and serves as a model system for studying structural and developmental evolution. Incorporation of the ribs into the turtle shell negates the costal movements that effect lung ventilation in other air-breathing amniotes. Instead, turtles have a unique abdominal-muscle-based ventilatory apparatus whose evolutionary origins have...
